电子综合设计新课题的开发与设计

Development and Design of a New Electronic Synthetic Project

详细地讨论了开发的一个电子综合设计新课题:超声波测距仪的设计与实现。该课题以单片机为中心,配以超声波发射、接收、放大电路,实现超声波回波信号接收,并测量收发之间的时间差,计算出发射点距障碍物的距离。通过教学实践表明,该课题可以有效地提高学生的动手实践能力,满足了电子综合设计课程的教学要求。

A new electronic synthetic design project is discussed in details in this paper in which includes designing and implementation of ultrasonic range finder.The project takes the MCU as the center,with the ultrasonic emission,receival and amplification circuit to receive the echo of the ultrasonic.By the measure of the time interval,it can compute the distance from the emission point to the roadblock.The teaching practice demonstrates that,the project can improve the hands-on practical ability of the students efficiently and meets the demand of the teaching of the electronic synthetic design course.
